I’m moving ahead with a mobile app that will launch simultaneously on iOS and Android, and its core revenue driver will be in-app purchases. The vision is straightforward: a polished, store-ready product that lets users buy digital content or subscriptions seamlessly while Apple’s StoreKit and Google Play Billing work reliably behind the scenes. To keep the codebase efficient I’m open to a shared framework such as Flutter or React Native, though I have no objection to fully native builds if you can demonstrate faster approval times or smoother performance. Whichever route you choose, the purchasing flow must be secure, receipt-validated, and easy for me to extend with new items later. Key deliverables • Complete, compilable source code for both platforms • Fully implemented in-app purchase flows (consumables, non-consumables or subscriptions as needed) with sandbox testing evidence • Receipt / purchase validation and graceful error handling • A brief deployment guide outlining certificates, provisioning, and store-listing steps Once these items are met and test transactions clear on both stores, we’re done. Let’s keep communication tight so the build ships quickly and passes review on the first attempt.

Hi there, I have read your project requirement carefully. You need a mobile application for iOS and Android with fully implemented in-app purchases (consumables, non-consumables, subscriptions), secure receipt validation, and a smooth, store-compliant purchase flow. We can build this using Flutter for a single codebase with native integrations for Apple StoreKit and Google Play Billing. The implementation will include complete purchase flows, server-side receipt validation for security, proper error handling, and a scalable structure to easily add new products later. The app will be tested in sandbox environments and prepared to meet App Store and Play Store review guidelines. A few questions to proceed further: ============================ What type of in-app purchases are you planning initially (subscriptions, one-time purchases, or both)? Do you already have developer accounts set up for Apple and Google? Do you need a backend for managing users, subscriptions, and validation, or only client-side validation? What is your expected timeline for launch? Best Regards, Srashtasoft Team

I can deliver a polished iOS and Android app with smooth, secure in-app purchases using either Flutter or React Native to keep the codebase lean and easy to extend. My approach includes full StoreKit and Google Play Billing integration, with receipt validation and clear error handling to avoid common pitfalls that cause review delays. I recently helped a client launch a subscription-based app on both stores that passed reviews first try. We used sandbox testing at every step to ensure the purchasing flow was rock-solid before submitting. For your app, I’d like to clarify: do you expect all purchase types (consumables, non-consumables, subscriptions) from day one, or should the app support adding new purchase types after launch? I’ll provide full source code plus a concise deployment guide covering certificates and listing steps so you can handle future updates confidently. We’ll keep communication tight to stick to deadlines and deliver a smooth launch. I’m ready to start building your store-ready app with a secure, extensible purchase system as soon as you are.

Hi, A store-ready iOS and Android app centered on in-app purchases demands airtight billing and fast review clearance. You require secure, receipt-validated flows plus sandbox proof, with a shared codebase that stays lean and extendable for new items while meeting Apple and Google standards. With 10 years shipping mobile products, I’ll build on Flutter to unify iOS and Android and leverage StoreKit and Google Play Billing for consumables, non-consumables, and subscriptions. I implement server-side receipt validation, graceful error handling, and modular purchase catalogs so you can add offerings without code churn. Past FinTech and subscription apps give me edge on compliance, review timing, and crash-free releases. Deliverables include compilable source, validated purchase flows with sandbox transaction logs, and a deployment guide covering certificates, provisioning, and store-listing steps. I keep communication tight and testing aggressive so the build ships quickly and passes review on the first attempt. Lets connect in chat so that we discuss further. Regards, Mohd Nadeem Khan

Hi, I’ve worked on a few mobile apps with in-app purchases before, so I’m pretty comfortable with both iOS and Android flows. For your project, I’d suggest going with React Native so we can keep a single codebase but still integrate properly with StoreKit and Google Play Billing. It’s a good balance between speed and stability. I can handle the full flow: Setting up products (consumable / subscription) Purchase + restore flow Handling edge cases (cancel, fail, pending…) Basic receipt validation Sandbox testing on both platforms I’ll also make sure the structure is clean so you can easily add new items later without touching too much code. I’ve done app submissions before, so I can guide you through the store setup as well to avoid common rejection issues. Happy to go over the requirements in more detail and align on the best approach.
